Abstract

At least a pair of connections ports having an inner diameter which is insertable into the end part of a tube are connected to each other by a tubular connection part to cause the joint body to be formed, and at the same time a tubular joint is constructed by integrally forming sealing members by extruding an elastomer resin to the inner circumferential face at the respective connection ports, whereby it is possible to reliably connect tubes in a short time even in a narrow working place and to improve the working efficiency, it is possible to perfectly stop water at the connection parts, and the connection state thereof is able to be maintained without fail for a longer period of time. Furthermore, no attaching work of sealing members is required at the connection ports, whereby the production costs of the products are able to be reduced. Still furthermore, it is possible to connect tubes in various arranged states with only a single kind of tubular joint.
